At present, most of the anti-peep films on the market are left and right for anti-peeping, so can the anti-peep film prevent it from getting up and down?



  The privacy screen can be divided into: a 45-degree anti-peep film on the left and right, a 30-degree anti-peep film on the left and right, a 30-degree anti-peep film on the top and bottom, and a 45-degree anti-peep film on the upper and lower sides. The upper and lower left and right anti-spy film, that is, the 4-way privacy screen, is made of a second layer of louver that is 90° from the vertical louver, because the additional louver layer makes the filter thicker, so the light transmittance is lowered. Make the screen look darker.
